On June 22, 2005, we completed our initial public offering and commenced operations. We operate as an externally managed, closed-end, non-diversified management investment company and have elected to be treated as a BDC under the Investment Company Act of 1940, as amended (the “1940 Act”). For U.S. federal income tax purposes, we have elected to be treated as a RIC under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”). To continue to qualify as a RIC for U.S. federal income tax purposes and obtain favorable RIC tax treatment, we must meet certain requirements, including certain minimum distribution requirements.\n\nAs of March 31, 2026, shares of our common stock, our 5.00% Notes due 2026 (“5.00% 2026 Notes”), our 4.875% Notes due 2028 (“4.875% 2028 Notes”), our 7.875% Notes due 2030 (\"7.875% 2030 Notes\") and our 7.125% Notes due 2031 (\"7.125% 2031 Notes\") are traded on the Nasdaq Global Select Market (“Nasdaq”) under the trading symbols “GAIN,” “GAINN,” “GAINZ,” \"GAINI,\" and \"GAING,\" respectively. Our 6.875% Notes due 2028 (\"6.875% 2028 Notes\") are not listed.\n\nInvestment Adviser and Administrator\n\nWe are externally managed by the Adviser, an affiliate of ours and an SEC-registered investment adviser, pursuant to an investment advisory and management agreement, as amended and/or restated from time to time (the “Advisory Agreement”). We have also entered into an administration agreement (the “Administration Agreement”) with Gladstone Administration, LLC (the “Administrator”), an affiliate of ours and the Adviser. Each of the Adviser and the Administrator are privately-held companies that are indirectly owned by David Gladstone, our chairman. David Dullum, our chief executive officer and president, also serves as the executive vice president of private equity of the Adviser. Erika Highland and Christopher Lee, both of whom are executive vice presidents, also serve as senior managing directors of the Adviser. Michael LiCalsi, our chief administrative officer, co-general counsel and co-secretary, also serves as the Administrator’s president, co-general counsel, and co-secretary, as well as the executive vice president of administration of the Adviser. Erich Hellmold, our co-general counsel and co-secretary, also serves in the same roles for the Administrator and Adviser. John Sateri, our chief investment officer, also serves in the same role for the Adviser. Mr. Gladstone also serves on the board of directors of the Adviser, the board of managers of the Administrator, and as an executive officer of the Adviser and the Administrator. The Administrator employs, among others, our chief financial officer and treasurer, chief valuation officer, chief compliance officer, chief administrative officer, co-general counsels and co-secretaries (one of whom also serves as the president of the Administrator) and their respective staffs. The Adviser and Administrator have extensive experience in our lines of business and also provide investment advisory and administrative services, respectively, to our affiliates, including: Gladstone Commercial Corporation (“Gladstone Commercial”), a publicly-traded real estate investment trust; Gladstone Capital Corporation (“Gladstone Capital”), a publicly-traded BDC and RIC; Gladstone Land Corporation (“Gladstone Land”), a publicly-traded real estate investment trust; and Gladstone Alternative Income Fund (\"Gladstone Alternative\"), a registered, non-diversified, closed-end management investment company that operates as an interval fund (together with “Gladstone Commercial,” “Gladstone Capital,” and \"Gladstone Land,\" collectively the “Affiliated Public Funds”). In the future, the Adviser and Administrator may provide investment advisory and administrative services, respectively, to other funds and companies, both public and private.\n\nThe Adviser was organized as a corporation under the laws of the State of Delaware on July 2, 2002, and is a SEC-registered investment adviser under the Investment Advisers Act of 1940, as amended. The Administrator was organized as a limited liability company under the laws of the State of Delaware on March 18, 2005. The Adviser and Administrator are headquartered in McLean, Virginia, a suburb of Washington, D.C. The Adviser also has offices in several other states.\n\n3\n\n[Table of Contents](#id4d58da65d414707b3cd9972f3050497_7)\n\nInvestment Objectives and Strategy\n\nWe were established for the purpose of investing in debt and equity securities of established private businesses operating in the United States (\"U.S.\"). Our investment objectives are to: (i) achieve and grow current income by investing in debt securities of established businesses that we believe will provide stable earnings and cash flow to pay expenses, make principal and interest payments on our outstanding indebtedness and make distributions to stockholders that grow over time; and (ii) provide our stockholders with long-term capital appreciation in the value of our assets by investing in equity securities of established businesses, generally in combination with the aforementioned debt securities, that we believe can grow over time to permit us to sell our equity investments for capital gains. To achieve our investment objectives, our investment strategy is to invest in several categories of debt and equity securities, with individual investments in a particular portfolio company generally totaling up to $75 million, although investment size may vary, depending upon our total assets or available capital at the time of investment. We expect that our investment portfolio over time will consist of approximately 70% in debt investments and 30% in equity investments, at cost. As of March 31, 2026, our investment portfolio was comprised of 70.8% in debt investments and 29.2% in equity investments, at cost.\n\nWe focus on investing in lower middle market private businesses (which we generally define as private companies with annual earnings before interest, taxes, depreciation and amortization (“EBITDA”) of $5 million to $25 million) (“Lower Middle Market”) in the U.S. that meet certain criteria, including: the sustainability of the business’ free cash flow and its ability to grow it over time, adequate assets for loan collateral, experienced management teams with a significant ownership interest in the portfolio company, reasonable capitalization of the portfolio company, including an ample equity contribution or cushion based on prevailing enterprise valuation multiples, and the potential to realize appreciation and gain liquidity in our equity position, if any. We anticipate that liquidity in our equity position will be achieved through a merger, acquisition, or recapitalization of the portfolio company, a public offering of the portfolio company’s stock, or, to a lesser extent, by exercising our right to require the portfolio company to repurchase our warrants, as applicable, though there can be no assurance that we will always have these rights. We invest in portfolio companies that seek funds for management buyouts and/or growth capital to finance acquisitions, recapitalize or, to a lesser extent, refinance their existing debt facilities. We seek to avoid investing in high-risk, early-stage enterprises. Our targeted portfolio companies are generally considered too small for the larger capital marketplace.\n\nWe invest by ourselves or jointly with other funds and/or management of the portfolio company, depending on the opportunity. In July 2012, the SEC granted us an exemptive order (the “Co-Investment Order”) that expanded our ability to co-invest, under certain circumstances, with certain of our affiliates, including Gladstone Capital and Gladstone Alternative and any future BDC or registered closed-end management investment company that is advised (or sub-advised if it controls the fund) by the Adviser, or any combination of the foregoing, subject to the conditions in the Co-Investment Order. In September 2025, the SEC granted us our current Co-Investment Order that contains a more flexible requirement that allocations be “fair and equitable” to us and that the Adviser consider the interests of us in allocations and which minimizes certain board approval requirements from the prior Co-Investment Order. We believe the Co-Investment Order has enhanced and will continue to enhance our ability to further our investment objectives and strategies. If we are participating in an investment with one or more co-investors, whether or not an affiliate of ours, our investment is likely to be smaller than if we were investing alone.\n\nIn general, our investments in debt securities have a term of five years, accrue interest at variable rates based on the 30 day Secured Overnight Financing Rate (\"SOFR\") and, to a lesser extent, at fixed rates. As of March 31, 2026, our loan portfolio consisted of 100.0% variable rate loans with floors.\n\nWe seek debt instruments that pay interest monthly or, at a minimum, quarterly, and which may include a yield enhancement such as a success fee or, to a lesser extent, deferred interest provision and are primarily interest only, with all principal and any accrued but unpaid interest due at maturity. Generally, success fees accrue at a set rate and are contractually due upon a change of control of the portfolio company. Some debt securities may have deferred interest whereby some portion of the interest payment is added to the principal balance so that the interest is paid, together with the principal, at maturity. This form of deferred interest is often called “paid-in-kind” (“PIK”) interest. As of March 31, 2026, we did not have any securities with a PIK feature.\n\nTypically, our investments in equity securities take the form of common stock, preferred stock, limited liability company interests, warrants or options to purchase any of the foregoing. Often, these equity investments occur in connection with our original investment, buyouts and recapitalizations of a business, or refinancing existing debt. From our initial public offering in 2005 through March 31, 2026, we have invested in 66 companies, excluding investments in syndicated loans.\n\n4\n\n[Table of Contents](#id4d58da65d414707b3cd9972f3050497_7)\n\nWe expect that our investment portfolio will continue to primarily include the following three categories of investments in private companies in the U.S.:\n\n•Secured First Lien Debt Securities: We seek to invest a portion of our assets in secured first lien debt securities also known as senior loans, senior term loans, lines of credit and senior notes. Using its assets as collateral, the borrower typically uses secured first lien debt to cover a substantial portion of the funding needs of the business. These debt securities usually take the form of first priority liens on all, or substantially all, of the assets of the business.\n\n•Secured Second Lien Debt Securities: We seek to invest a portion of our assets in secured second lien debt securities, which may also be referred to as subordinated loans, subordinated notes and mezzanine loans. These secured second lien debt securities rank junior to the borrower’s secured first lien debt securities and may be secured by second priority liens on all or a portion of the assets of the business. Additionally, we may receive other yield enhancements in addition to or in lieu of success fees, such as warrants to buy common and preferred stock or limited liability interests, in connection with these secured second lien debt securities.\n\n•Preferred and Common Equity/Equivalents: We seek to invest a portion of our assets in equity securities, which consist of preferred and common equity, limited liability company interests, warrants or options to acquire such securities, and are generally in combination with our debt investment in a business. Additionally, we may receive equity investments derived from restructurings on some of our existing debt investments. In many cases, we will own a significant portion of the equity of the businesses in which we invest.\n\nWe expect that most, if not all, of the debt securities we acquire will not be rated by a rating agency. Investors should assume that these loans would be rated below what is considered “investment grade” quality. Investments rated below investment grade are often referred to as high yield securities or junk bonds and may be considered higher risk as compared to investment grade debt instruments.\n\nInvestment Policies\n\nWe seek to achieve a high level of current income and capital gains through investments in secured debt securities and preferred and common stock that we generally acquire in connection with buyouts and other recapitalizations. The following investment policies, along with the investment objectives, may not be changed without the approval of our board of directors (our “Board of Directors”), a majority of whom are not “interested persons” as defined in Section 2(a)(19) of the 1940 Act:\n\n•We will at all times conduct our business so as to retain our status as a BDC. See “—Regulation as a BDC — Qualifying Assets.”\n\n•We will at all times endeavor to conduct our business so as to retain our status as a RIC under the Code. See \"—Material U.S. Federal Income Tax Considerations.\"\n\nWith the exception of our policy to conduct our business as a BDC, these investment policies are not fundamental and may be changed without stockholder approval.\n\nInvestment Concentrations\n\nAs of March 31, 2026, our investment portfolio consisted of investments in 29 portfolio companies located in 20 states and Canada across 16 different industries with an aggregate fair value of $1.3 billion. Our investments in SFEG Holdings, Inc. (\"SFEG\"), The E3 Company, LLC (\"E3\"), Schylling, Inc. (\"Schylling\"), Brunswick Bowling Products, Inc. (\"Brunswick\"), and Detroit Defense, Inc. (\"Detroit Defense\") represented our five largest portfolio investments at fair value and collectively comprised $582.6 million, or 44.5%, of our total investment portfolio at fair value as of March 31, 2026.\n\n5\n\n[Table of Contents](#id4d58da65d414707b3cd9972f3050497_7)\n\nThe following table summarizes our investments by security type as of March 31, 2026 and 2025:\n\nMarch 31, 2026March 31, 2025\n\nCostFair ValueCostFair Value\n\nSecured first lien debt$593,008 56.3 %$570,602 43.6 %$584,026 62.2 %$514,334 52.5 %\n\nSecured second lien debt152,840 14.5 %99,197 7.6 %103,956 11.1 %103,580 10.6 %\n\nTotal debt745,848 70.8 %669,799 51.2 %687,982 73.3 %617,914 63.1 %\n\nPreferred equity257,403 24.5 %426,949 32.6 %201,487 21.5 %302,163 30.9 %\n\nCommon equity/equivalents49,597 4.7 %212,500 16.2 %49,597 5.2 %59,243 6.0 %\n\nTotal equity/equivalents307,000 29.2 %639,449 48.8 %251,084 26.7 %361,406 36.9 %\n\nTotal investments\n$1,052,848 100.0 %$1,309,248 100.0 %$939,066 100.0 %$979,320 100.0 %\n\nOur investments at fair value consisted of the following industry classifications as of March 31, 2026 and 2025:\n\nMarch 31, 2026\n\nMarch 31, 2025\n\nFair Value\nPercentage of\n\nTotal Investments\nFair ValuePercentage of\nTotal Investments\n\nMachinery (Non-Agriculture, Non-Construction, and Non-Electronic)$258,692 19.8 %$105,432 10.8 %\n\nDiversified/Conglomerate Services189,148 14.4 %170,360 17.4 %\n\nAerospace and Defense174,542 13.4 %107,869 10.9 %\n\nHome and Office Furnishings, Housewares, and Durable Consumer Products166,553 12.7 %159,236 16.3 %\n\nOil and Gas125,605 9.6 %69,589 7.1 %\n\nLeisure, Amusement, Motion Pictures, and Entertainment105,339 8.0 %78,460 8.0 %\n\nBuildings and Real Estate68,987 5.3 %69,320 7.1 %\n\nElectronics62,723 4.8 %71,573 7.2 %\n\nChemicals, Plastics, and Rubber49,715 3.8 %11,612 1.2 %\n\nHealthcare, Education, and Childcare41,630 3.2 %51,501 5.3 %\n\nMining, Steel, Iron and Non-Precious Metals37,713 2.9 %41,010 4.2 %\n\nPrinting and Publishing8,379 0.6 %11,681 1.2 %\n\nTelecommunications7,942 0.6 %7,585 0.8 %\n\nDiversified/Conglomerate Manufacturing6,763 0.5 %6,493 0.7 %\n\nOther < 2.0%5,517 0.4 %17,599 1.8 %\n\nTotal investments\n$1,309,248 100.0 %$979,320 100.0 %\n\nOur investments at fair value were included in the following geographic regions of the U.S. and Canada as of March 31, 2026 and 2025:\n\nMarch 31, 2026March 31, 2025\n\nLocation\nFair ValuePercentage of\nTotal InvestmentsFair ValuePercentage of\nTotal Investments\n\nUnited States\n\nSouth$649,436 49.6 %$317,294 32.4 %\n\nWest227,294 17.3 %222,062 22.7 %\n\nMidwest216,726 16.6 %227,415 23.2 %\n\nNortheast193,837 14.8 %182,669 18.7 %\n\nCanada21,955 1.7 %29,880 3.0 %\n\nTotal investments\n$1,309,248 100.0 %$979,320 100.0 %\n\nThe geographic region indicates the location of the headquarters for our portfolio companies.

The Adviser’s investment professionals review information received from these and other sources in search of potential financing opportunities. If a potential opportunity matches our investment objectives, the investment professionals will seek an initial screening of the opportunity with our chief executive officer and president, David Dullum, to authorize the submission of an indication of interest (“IOI”) to the prospective portfolio company. If the prospective portfolio company passes this initial screening and the IOI is accepted by the prospective company, the investment professionals will seek approval to issue a letter of intent (“LOI”) from the Adviser’s investment committee, which currently is composed of Messrs. Gladstone, Dullum and John Sateri, as well as Laura Gladstone. If this LOI is issued, then the Adviser and Gladstone Securities, LLC (“Gladstone Securities”) (collectively, the “Due Diligence Team”) will conduct a due diligence investigation and create a detailed profile summarizing the prospective portfolio company’s historical financial statements, industry, competitive position and management team and analyzing its conformity to our general investment criteria. The investment professionals then present this profile to the Adviser’s investment committee, which must approve each investment.\n\nProspective Portfolio Company Characteristics\n\nWe have identified certain characteristics that we believe are important in identifying and investing in prospective portfolio companies. The criteria listed below provide general guidelines for our investment decisions, although not all of these criteria may be met by each portfolio company.\n\n•Experienced Management: We typically require that the companies in which we invest have experienced management teams or a hiring plan in place to install an experienced management team. We also require the companies to have in place proper incentives to induce management to succeed and act in concert with our interests as an investor, including having significant equity or other interests in the financial performance of their companies.\n\n•Value- and Income-Orientation and Positive Cash Flow: Our investment philosophy places a premium on fundamental analysis from an investor’s perspective and has a distinct value- and income-orientation. In seeking value, we focus on established companies in which we can invest at relatively low multiples of EBITDA, and that have positive operating cash flow at the time of investment. In seeking income, we typically invest in companies that generate relatively stable to growing sales, cash flows, and EBITDA to fixed charges coverage, which provides some assurance that the companies will be able to service their debt. We do not expect to invest in high-risk early stage companies or companies with what we believe to be speculative business plans.\n\n•Strong Competitive Position in an Industry: We seek to invest in companies that have developed strong market positions and significant relative market share within their respective markets and that we believe are well-positioned to capitalize on growth opportunities. We seek companies that demonstrate significant competitive advantages versus their competitors, which we believe will help to protect their market positions and profitability.\n\n•Enterprise Collateral Value: The projected enterprise valuation of the business, based on market based comparable cash flow multiples, is an important factor in our investment analysis in determining the collateral coverage of our debt securities.\n\nExtensive Due Diligence\n\nThe Due Diligence Team conducts what we believe are extensive evaluation and due diligence investigations of our prospective portfolio companies and investment opportunities. The due diligence investigation typically begins with a review of publicly available information followed by in-depth business analysis, including some or all of the following:\n\n•review of the prospective portfolio company’s historical and projected financial information, including a quality of earnings analysis;\n\n•visits to the prospective portfolio company’s business site(s) and evaluation of potential environmental issues;\n\n7\n\n[Table of Contents](#id4d58da65d414707b3cd9972f3050497_7)\n\n•interviews with the prospective portfolio company’s management, employees, customers and vendors;\n\n•review of loan documents and material contracts;\n\n•background checks and a management capabilities assessment on the prospective portfolio company’s management team; and\n\n•research, including market analyses, on the prospective portfolio company’s products, services or particular industry and its competitive position therein.\n\nUpon completion of a due diligence investigation and a decision to proceed with an investment, the Adviser’s investment professionals, who have primary responsibility for the investment, present the investment opportunity to the Adviser’s investment committee. The investment committee then determines whether to pursue the potential investment. Prior to the closing of an investment, additional due diligence may be conducted on our behalf by attorneys, independent accountants, and other outside advisers, as appropriate.\n\nWe also rely on the long-term relationships that the Adviser’s investment professionals have with leveraged buyout funds, investment bankers, commercial bankers, private equity sponsors, attorneys, accountants, and business brokers. In addition, the extensive direct experiences of our executive officers and managing directors in the operations of Lower Middle Market companies and providing debt and equity capital to Lower Middle Market companies plays a significant role in our investment evaluation and assessment of risk.\n\nInvestment Structure\n\nOnce the Adviser has determined that an investment meets our standards and investment criteria, the Adviser works with the management of that company and other capital providers to structure the transaction in a way that we believe will provide us with the greatest opportunity to maximize our return on the investment, while providing appropriate incentives to management of the company. As discussed above, the capital classes through which we typically structure a deal include secured first lien debt, secured second lien debt, and preferred and common equity or equivalents. Through its risk management process, the Adviser seeks to limit the downside risk of our investments by:\n\n•making investments with an expected total return (including interest, yield enhancements and potential equity appreciation) that it believes compensates us for the credit risk of the investment;\n\n•seeking collateral or superior positions in the portfolio company’s capital structure where possible;\n\n•incorporating put and call protection rights into the investment where possible;\n\n•negotiating covenants in connection with our investments that afford our portfolio companies as much flexibility as possible in managing their businesses, while also preserving our capital; and\n\n•holding board seats or securing board observation rights at the portfolio company.\n\nWe expect to hold most of our debt investments until maturity or repayment, but we may sell our investments (including our equity investments) earlier if a liquidity event takes place, such as a recapitalization of a portfolio company, an initial public offering, or a sale to a third party, including strategic buyers, private equity funds, or existing investors in the portfolio company, and which may be privately negotiated transactions.\n\n8\n\n[Table of Contents](#id4d58da65d414707b3cd9972f3050497_7)\n\nCompetitive Advantages\n\nA large number of entities compete with us and make the types of investments that we seek to make in Lower Middle Market companies. Such competitors include private equity funds, leveraged buyout funds, other BDCs, other equity and non-equity based investment funds, and other financing sources, including commercial banks. Many of our competitors are substantially larger than we are and have considerably greater funding sources or are able to access capital more cost effectively. In addition, certain of our competitors may have higher risk tolerances or different risk assessments, which could allow them to consider a wider variety of investments and establish a larger portfolio of investments. Furthermore, many of these competitors are not subject to the regulatory restrictions that the 1940 Act imposes on us as a BDC. However, we believe that we have the following competitive advantages over many other providers of financing to Lower Middle Market companies.\n\nManagement Expertise\n\nOur Adviser has a separate investment committee for the Company and each of the Affiliated Public Funds. The Adviser's investment committee for the Company is comprised of Messrs. Gladstone, Dullum and Sateri and Ms. Gladstone, each of whom have a wealth of experience in our area of operation. Ms. Gladstone and Messrs. Gladstone and Sateri also serve on the Adviser’s investment committee for the other Affiliated Public Funds. Ms. Gladstone has over 20 years of experience in investing in middle market companies and is a managing director of the Adviser. Each of Messrs. Gladstone, Dullum and Sateri have over 30 years of experience in investing in middle market companies and with operating in the BDC marketplace in general. Mr. Gladstone also has principal management responsibility for the Adviser as an executive officer, and has worked at the Gladstone companies for more than 20 years. These four individuals dedicate a significant portion of their time to managing our investment portfolio. Our senior management has extensive experience providing capital to Lower Middle Market companies. In addition, we have access to the resources and expertise of the Adviser’s investment professionals and support staff who possess a broad range of transactional, financial, managerial, and investment skills.\n\nIncreased Access to Investment Opportunities Developed Through Extensive Research Capability and Network of Contacts\n\nThe Adviser seeks to identify potential investments through active origination and due diligence and through its dialogue with numerous management teams, members of the financial community and potential corporate partners with whom the Adviser’s investment professionals have long-term relationships. We believe that the Adviser’s investment professionals have developed a broad network of contacts within the investment, commercial banking, private equity and investment management communities, and that their reputation, experience, and focus on investing in Lower Middle Market companies enables us to source and identify well-positioned prospective portfolio companies, which provide attractive investment opportunities. Additionally, the Adviser expects to generate information from its professionals’ network of accountants, consultants, lawyers and management teams of portfolio companies and other contacts to support the Adviser’s investment activities.\n\nDisciplined, Value- and Income-Oriented Investment Philosophy with a Focus on Preservation of Capital\n\nIn making its investment decisions, the Adviser focuses on the risk and reward profile of each prospective portfolio company, seeking to minimize the risk of capital loss without foregoing the potential for capital appreciation. We expect the Adviser to use the same investment philosophy that its professionals use in the management of the other Affiliated Public Funds and to commit resources to manage downside exposure. The Adviser’s approach seeks to reduce our risk in investments by using some or all of the following approaches:\n\n•focusing on companies with attractive and sustainable market positions and cash flow;\n\n•investing in companies with experienced and established management teams;\n\n•engaging in extensive due diligence from the perspective of a long-term investor;\n\n•investing at low price-to-cash flow multiples; and\n\n•adopting flexible transaction structures by drawing on the experience of the investment professionals of the Adviser and its affiliates.\n\n9\n\n[Table of Contents](#id4d58da65d414707b3cd9972f3050497_7)\n\nLonger Investment Horizon\n\nUnlike private equity and other funds that are typically organized as finite-life partnerships (generally seven to ten years), we are not subject to standard periodic capital return requirements. These structures often force private equity and other funds to seek returns on their investments by causing their portfolio companies to pursue mergers, public equity offerings, or other liquidity events more quickly than might otherwise be optimal or desirable, potentially resulting in a lower overall return to investors and/or an adverse impact on their portfolio companies. In contrast, we are an exchange-traded corporation of perpetual duration. We believe that our flexibility to make investments with a long-term view and without the capital return requirements of traditional private investment vehicles provides us with the opportunity to achieve greater long-term returns on invested capital.\n\nFlexible Transaction Structuring\n\nWe believe the Adviser’s and our management team’s broad expertise and years of combined experience enable the Adviser to identify, assess, and structure investments successfully across all levels of a company’s capital structure and manage potential risk and return at all stages of the economic cycle. We are not subject to many of the regulatory limitations that govern traditional lending institutions, such as banks. As a result, we are flexible in selecting and structuring investments, adjusting investment criteria and transaction structures and, in some cases, the types of securities in which we invest, thereby affording us a competitive advantage of providing both, equity and debt financing, which may limit uncertainty related to the close of the transaction and the risk of refinancing during periods of market yield compression. We believe that this approach enables the Adviser to craft a financing structure which best fits the investment and growth profile of the underlying business and yields attractive investment opportunities that will continue to generate current income and capital gain potential throughout the economic cycle, including during turbulent periods in the capital markets.\n\nOngoing Management of Investments and Portfolio Company Relationships\n\nThe Adviser’s investment professionals actively oversee each investment by continuously evaluating the portfolio company’s performance and typically working collaboratively with the portfolio company’s management to identify and incorporate best resources and practices that help us achieve our projected investment performance.\n\nMonitoring\n\nThe Adviser’s investment professionals monitor the financial performance, trends, and changing risks of each portfolio company on an ongoing basis to determine if each portfolio company is performing within expectations and to guide the portfolio company’s management in taking the appropriate courses of action. The Adviser employs various methods of evaluating and monitoring the performance of our investments in portfolio companies, which can include the following:\n\n•monthly analysis of financial and operating performance;\n\n•frequent assessment of the portfolio company’s performance against its business plan and our investment expectations;\n\n•attendance at and/or participation in the portfolio company’s board of directors or management meetings;\n\n•assessment of portfolio company management, governance and strategic direction;\n\n•assessment of the portfolio company’s industry and competitive environment; and\n\n•review and assessment of the portfolio company’s operating outlook and financial projections.\n\nRelationship Management\n\nThe Adviser’s investment professionals interact with various parties involved with a portfolio company, or investment, by actively engaging with internal and external constituents, including:\n\n•management;\n\n10\n\n[Table of Contents](#id4d58da65d414707b3cd9972f3050497_7)\n\n•boards of directors;\n\n•financial sponsors;\n\n•capital partners;\n\n•auditors; and\n\n•advisers and consultants.\n\nManagerial Assistance and Services\n\nAs a BDC, we make available significant managerial assistance, as defined in the 1940 Act, to our portfolio companies and provide other services (other than such managerial assistance) to such portfolio companies. Neither we, nor the Adviser, currently receive fees in connection with the managerial assistance we make available. At times, the Adviser may also provide other services to our portfolio companies under certain agreements and may receive fees for services other than managerial assistance. Such services may include: (i) assistance obtaining, sourcing or structuring credit facilities, long term loans or additional equity from unaffiliated third parties; (ii) negotiating important contractual financial relationships; (iii) consulting services regarding restructuring of the portfolio company and financial modeling as it relates to raising additional debt and equity capital from unaffiliated third parties; and (iv) a primary role in interviewing, vetting and negotiating employment contracts with candidates in connection with adding and retaining key portfolio company management team members. The Adviser non-contractually, unconditionally, and irrevocably credits 100% of any fees received for such services against the base management fee that we would otherwise be required to pay to the Adviser, as discussed below in “—Transactions with Related Parties – Investment Advisory and Management Agreement – Base Management Fee;” however, pursuant to the terms of the Advisory Agreement, a small percentage of certain of such fees is retained by the Adviser in the form of reimbursement, at cost, for tasks completed by personnel of the Adviser, primarily related to the valuation of portfolio companies.\n\nGladstone Securities also provides other services (such as investment banking and due diligence services) to certain of our portfolio companies and receives fees for the provision of such services, see “—Transactions with Related Parties – Other Transactions” below.\n\nValuation Process\n\nOur Board of Directors has approved investment valuation policies and procedures pursuant to Rule 2a-5 (the “Policy”) and designated the Adviser to serve as the Board of Directors’ valuation designee (“Valuation Designee”) under the 1940 Act.\n\nThe following is a general description of the Policy that the professionals of the Adviser and Administrator, with oversight and direction from our chief valuation officer, an employee of the Administrator that reports directly to our Board of Directors (collectively, the “Valuation Team”), use each quarter to determine the fair value of our investment portfolio. In accordance with the 1940 Act, our Board of Directors has the ultimate responsibility for reviewing the good faith fair value determination of our investments for which market quotations are not readily available based on our Policy and for overseeing the Valuation Designee. The Adviser values our investments in accordance with the requirements of the 1940 Act and accounting principles generally accepted in the U.S. (“GAAP”). There is no single standard for determining fair value (especially for privately-held businesses), as fair value depends upon the specific facts and circumstances of each individual investment. Each quarter, our Board of Directors reviews the Policy to determine if changes thereto are advisable and whether the Valuation Team has applied the Policy consistently. With respect to the valuation of our investment portfolio, the Valuation Team performs the following steps each quarter:\n\n•Each investment is initially assessed by the Valuation Team using the Policy, which may include:\n\n•obtaining fair value quotes or utilizing valuation inputs from third party valuation firms; and\n\n•using techniques, such as total enterprise value, yield analysis, market quotes and other factors, including but not limited to: the nature and realizable value of the collateral, including external parties’ guaranties; any relevant offers or letters of intent to acquire the portfolio company; and the markets in which the portfolio company operates.\n\n11\n\n[Table of Contents](#id4d58da65d414707b3cd9972f3050497_7)\n\n•Preliminary valuation conclusions are then discussed amongst the Valuation Team and with our management and documented for review by our Board of Directors. Fair value determinations and supporting material are sent to the Board of Directors in advance of its quarterly meetings.\n\n•The Valuation Committee of the Board of Directors (comprised entirely of independent directors) meets to review the valuation determinations and supporting materials, discusses the information provided by the Valuation Team, determines whether the Valuation Team has followed the Policy and reviews other facts and circumstances, including current valuation risks, conflicts of interest, material valuation matters, appropriateness of valuation methodologies, back-testing results, price challenges/overrides, and ongoing monitoring and oversight of pricing services. After the Valuation Committee concludes its meeting, it and the chief valuation officer, representing the Valuation Designee, present the Valuation Committee’s findings on the Valuation Designee's determinations to the entire Board of Directors so that the full Board of Directors may review the Valuation Designee's determined fair values of such investments in accordance with the Policy.\n\nFair value measurements of our investments may involve subjective judgments and estimates and, due to the uncertainty inherent in valuing these securities, the determinations of fair value may fluctuate from period to period and may differ materially from the values that could be obtained if a ready market for these securities existed. Our net asset value (“NAV”) could be materially affected if the determinations regarding the fair value of our investments are materially different from the values that we ultimately realize upon our disposal of such securities. Our valuation policies, procedures and processes are more fully described in Note 2 — Summary of Significant Accounting Policies in our accompanying Notes to Consolidated Financial Statements included elsewhere in this Annual Report.\n\nTransactions with Related Parties\n\nInvestment Advisory and Management Agreement\n\nPursuant to our Advisory Agreement, which was most recently amended and restated in January 2025, we pay the Adviser certain fees as compensation for its services, consisting of a base management fee and an incentive fee, each as described below. On July 10, 2025, our Board of Directors, including a majority of the directors who are not parties to the Advisory Agreement or interested persons of either party, unanimously approved the renewal of the Advisory Agreement through August 31, 2026. Our Board of Directors considered the following factors as the basis for its decision to approve the Advisory Agreement: (1) the nature, extent and quality of services provided by the Adviser to our stockholders, (2) the investment performance of the Company and the Adviser, (3) the costs of the services to be provided and profits to be realized by the Adviser and its affiliates from the relationship with the Company, (4) the extent to which economies of scale will be realized as the Company and the Affiliated Public Funds grow and whether the fee level under the Advisory Agreement reflects the economies of scale for the Company’s investors, (5) the fee structure of the advisory and administrative agreements of comparable funds, (6) indirect profits to the Adviser created through the Company and (7) in light of the foregoing considerations, the overall fairness of the advisory fees paid under the Advisory Agreement.\n\nBased on the information reviewed and the considerations detailed above, our Board of Directors, including all of the directors who are not “interested persons” as that term is defined in the 1940 Act, concluded that the investment advisory fee rates and terms are fair and reasonable in relation to the services provided and approved the Advisory Agreement, as being in the best interests of our stockholders.\n\nBase Management Fee\n\nThe base management fee is payable quarterly to the Adviser pursuant to our Advisory Agreement and is assessed at an annual rate of 2.0%, computed on the basis of the value of our average gross assets at the end of the two most recently completed quarters (inclusive of the current quarter), which are total assets, including investments made with proceeds of borrowings, less any uninvested cash or cash equivalents resulting from borrowings, valued at the end of the applicable quarters within the respective period, and adjusted appropriately for any share issuances or repurchases during the period.\n\nAdditionally, as stated above, pursuant to the requirements of the 1940 Act, the Adviser makes available significant managerial assistance to our portfolio companies. The Adviser may also provide other services to our portfolio companies under certain agreements and may receive fees for services other than managerial assistance. Such services may include: (i) assistance obtaining, sourcing or structuring credit facilities, long term loans or additional equity from unaffiliated third parties; (ii) negotiating important contractual financial relationships; (iii) consulting services regarding restructuring of the portfolio company and financial modeling as it relates to raising additional debt and equity capital from unaffiliated third\n\n12\n\n[Table of Contents](#id4d58da65d414707b3cd9972f3050497_7)\n\nparties; and (iv) a primary role in interviewing, vetting and negotiating employment contracts with candidates in connection with adding and retaining key portfolio company management team members. The Adviser non-contractually, unconditionally, and irrevocably credits 100% of any fees received for such services against the base management fee that we would otherwise be required to pay to the Adviser; however, pursuant to the terms of the Advisory Agreement, a small percentage of certain of such fees is retained by the Adviser in the form of reimbursement, at cost, for tasks completed by personnel of the Adviser, primarily related to the valuation of portfolio companies. Loan servicing fees that are payable to the Adviser pursuant to our Fifth Amended and Restated Credit Agreement, as amended (the “Credit Facility”), are also 100% credited against the base management fee as discussed below “—Loan Servicing Fee Pursuant to Credit Facility.”\n\nIncentive Fee\n\nThe incentive fee payable to the Adviser under our Advisory Agreement consists of two parts: an income-based incentive fee and a capital gains-based incentive fee.\n\nThe income-based incentive fee rewards the Adviser if our quarterly net investment income (before giving effect to any incentive fee) exceeds 1.75% of our net assets, which we define as total assets less indebtedness and before taking into account any incentive fees payable or contractually due but not payable during the period, at the end of the immediately preceding calendar quarter, adjusted appropriately for any share issuances or repurchases during the period (the “Hurdle Rate”). The income-based incentive fee with respect to our pre-incentive fee net investment income is payable quarterly to the Adviser and is computed as follows:\n\n•No incentive fee in any calendar quarter in which our pre-incentive fee net investment income does not exceed the Hurdle Rate;\n\n•100.0% of our pre-incentive fee net investment income with respect to that portion of such pre-incentive fee net investment income, if any, that exceeds the Hurdle Rate but is less than 2.1875% of our net assets, adjusted appropriately for any share issuances or repurchases during the period, in any calendar quarter; and\n\n•20.0% of the amount of our pre-incentive fee net investment income, if any, that exceeds 2.1875% of our net assets, adjusted appropriately for any share issuances or repurchases during the period, in any calendar quarter.\n\nFor this purpose, pre-incentive fee net investment income means interest income, dividend income and any other income (including any other fees, such as commitment, origination, structuring, diligence, consulting fees that we receive from portfolio companies, but excluding fees for providing managerial assistance) accrued by us during the calendar quarter, minus our operating expenses for the quarter. Pre-incentive fee net investment income includes, in the case of investments with a deferred interest feature (such as original issue discount, debt instruments with payment-in-kind interest and zero coupon securities), accrued income that we have not yet received in cash. Pre-incentive fee net investment income does not include any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation.\n\nQuarterly Incentive Fee Based on Net Investment Income\n\nPre-incentive fee net investment income\n\n(expressed as a percentage of the value of net assets)\n\nPercentage of pre-incentive fee net investment income\n\nallocated to income-related portion of incentive fee\n\nThe second part of the incentive fee is a capital gains-based incentive fee that is determined and payable in arrears as of the end of each fiscal year (or upon termination of the Advisory Agreement, as of the termination date), and equals 20.0% of our realized capital gains, less any realized capital losses and unrealized depreciation, calculated as of the end of the preceding calendar year. The capital gains-based incentive fee payable to the Adviser is calculated based on (i) cumulative aggregate realized capital gains since our inception, less (ii) cumulative aggregate realized capital losses since our inception, less (iii) the entire portfolio’s aggregate unrealized capital depreciation, if any, as of the date of the calculation. If this number is positive at the applicable calculation date, then the capital gains-based incentive fee for such year equals 20.0% of such amount, less the aggregate amount of any capital gains-based incentive fees paid in respect of our portfolio\n\n13\n\n[Table of Contents](#id4d58da65d414707b3cd9972f3050497_7)\n\nin all prior years. For calculation purposes, cumulative aggregate realized capital gains, if any, equals the sum of the excess between the net sales price of each investment, when sold, and the original cost of such investment since our inception. Cumulative aggregate realized capital losses equals the sum of the deficit between the net sales price of each investment, when sold, and the original cost of such investment since our inception. The entire portfolio’s aggregate unrealized capital depreciation, if any, equals the sum of the deficit between the fair value of each investment security as of the applicable calculation date and the original cost of such investment security. For the year ended March 31, 2026, no capital gains-based incentive fees were contractually due and paid to the Adviser. For the years ended March 31, 2025 and 2024, capital gains-based incentive fees of $4.9 million and $1.1 million, respectively, were contractually due and paid to the Adviser.\n\nIn accordance with GAAP, accrual of the capital gains-based incentive fee is determined as if our investments had been liquidated at their fair values as of the end of the reporting period. Therefore, GAAP requires that the capital gains-based incentive fee accrual consider the aggregate unrealized capital appreciation in the calculation, as a capital gains-based incentive fee would be payable if such unrealized capital appreciation were realized. There can be no assurance that any such unrealized capital appreciation will be realized in the future. Accordingly, a GAAP accrual is calculated at the end of the reporting period based on (i) cumulative aggregate realized capital gains since our inception, plus (ii) the entire portfolio’s aggregate unrealized capital appreciation, if any, less (iii) cumulative aggregate realized capital losses since our inception, less (iv) the entire portfolio’s aggregate unrealized capital depreciation, if any. If such amount is positive at the end of a reporting period, a capital gains-based incentive fee equal to 20.0% of such amount, less the aggregate amount of capital gains-based incentive fees accrued in all prior years, is recorded, regardless of whether such amount is contractually due under the terms of the Advisory Agreement. If such amount is negative, then there is no accrual for such period and prior period accruals are reversed, as appropriate. For the years ended March 31, 2026, 2025 and 2024, we recorded capital gains-based incentive fees of $38.0 million, $7.4 million and $12.7 million, respectively.\n\nLoan Servicing Fee Pursuant to Credit Facility\n\nThe Adviser also services the loans held by our wholly-owned subsidiary, Gladstone Business Investment, LLC (“Business Investment”) (the borrower under our Credit Facility), in return for which the Adviser receives a 2.0% annual fee based on the monthly aggregate outstanding balance of loans pledged under our Credit Facility. Since Business Investment is a consolidated subsidiary of ours, coupled with the fact that the total base management fee paid to the Adviser pursuant to the Advisory Agreement cannot exceed 2.0% of total assets (less any uninvested cash or cash equivalents resulting from borrowings) during any given calendar year, we treat the payment of the loan servicing fee pursuant to our Credit Facility as a pre-payment of the base management fee under the Advisory Agreement. Accordingly, these loan servicing fees are 100% non-contractually, unconditionally, and irrevocably credited back to us by the Adviser.\n\nAdministration Agreement\n\nWe reimburse the Administrator pursuant to the Administration Agreement for our allocable portion of the Administrator’s expenses incurred while performing services to us, which are primarily rent and salaries and benefits expenses of the Administrator’s employees, including our chief financial officer and treasurer, chief valuation officer, chief compliance officer, chief administrative officer, co-general counsels and co-secretaries (who also serves as the Administrator’s co-general counsels and co-secretaries, and one of whom serves as the Administrator's president), and their respective staffs.\n\nOur allocable portion of the Administrator’s expenses is generally derived by multiplying the Administrator’s total expenses by the approximate percentage of time during the current quarter that the Administrator’s employees performed services for us in relation to their time spent performing services for all companies serviced by the Administrator. On July 10, 2025, our Board of Directors, including a majority of the directors who are not parties to the Administration Agreement or interested persons of either party, approved the annual renewal of the Administration Agreement through August 31, 2026. For the years ended March 31, 2026, 2025 and 2024, administration fees were $2.0 million, $1.9 million and $1.8 million, respectively.\n\n14\n\n[Table of Contents](#id4d58da65d414707b3cd9972f3050497_7)\n\nOther Transactions\n\nMr. Gladstone also serves on the board of managers of our affiliate Gladstone Securities, a privately-held broker-dealer registered with the Financial Industry Regulatory Authority and insured by the Securities Investor Protection Corporation. Gladstone Securities is 100% indirectly owned and controlled by Mr. Gladstone and has provided other services, such as investment banking and due diligence services, to certain of our portfolio companies, for which Gladstone Securities receives a fee. Any such fees paid by portfolio companies to Gladstone Securities do not impact the fees we pay to the Adviser or the non-contractual, unconditional, and irrevocable credits against the base management fee. For additional information, refer to Note 4 — Related Party Transactions in the accompanying Notes to Consolidated Financial Statements.\n\nMaterial U.S. Federal Income Tax Considerations\n\nThis is a general summary of certain material U.S. federal income tax considerations applicable to us, to our qualification and taxation as a RIC for U.S. federal income tax purposes under Subchapter M of the Code and to the ownership and disposition of our shares. This summary does not purport to be a complete description of all of the tax considerations relating thereto. In particular, we have not described certain considerations that may be relevant to certain types of stockholders subject to special treatment under U.S. federal income tax laws. This summary does not discuss any aspect of state, local or foreign tax laws, or the U.S. estate or gift tax. Stockholders are urged to consult their tax advisors regarding their particular situations and the possible applicability of federal, state, local, non-U.S. or other tax laws, and any proposed tax law changes.\n\nFor purposes of this summary, a “U.S. stockholder” is a beneficial owner of stock that is for U.S. federal income tax purposes:\n\n•an individual who is a citizen or resident of the United States;\n\n•a corporation, or other entity treated as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States or any state thereof of the District of Columbia;\n\n•a trust, if a court within the United States is able to exercise primary supervision over its administration and one or more U.S. persons (as defined in the Code) have the authority to control all of its substantial decisions, or if the trust has a valid election in effect under applicable U.S. Treasury regulations to be treated as a domestic trust for U.S. federal income tax purposes; or\n\n•an estate, the income of which is subject to U.S. federal income taxation regardless of its source.\n\nRIC Status\n\nTo qualify for treatment as a RIC under Subchapter M of the Code, we must generally distribute to our stockholders, for each taxable year, at least 90% of our taxable ordinary income plus the excess of our realized net short-term capital gains over our realized net long-term capital losses (“Investment Company Taxable Income”). We refer to this as the “annual distribution requirement.” We must also meet several additional requirements, including:\n\n•Business Development Company status: At all times during the taxable year, we must maintain our status as a BDC.\n\n•Income source requirements: At least 90% of our gross income for each taxable year must be from dividends, interest, payments with respect to securities, loans, gains from sales or other dispositions of securities or other income (including certain deemed inclusions) derived with respect to our business of investing in securities, and net income derived from an interest in a qualified publicly-traded partnership.\n\n•Asset diversification requirements: As of the close of each quarter of our taxable year: (1) at least 50% of the value of our assets must consist of cash, cash items, U.S. government securities, the securities of other regulated investment companies and other securities to the extent that (a) we do not hold more than 10% of the outstanding voting securities of an issuer of such other securities and (b) such other securities of any one issuer do not represent more than 5% of our total assets (the “50% threshold”), and (2) no more than 25% of the value of our total assets may be invested in the securities (other than U.S. government securities or the securities of other\n\n15\n\n[Table of Contents](#id4d58da65d414707b3cd9972f3050497_7)\n\nregulated investment companies) of (i) one issuer, (ii) two or more issuers that are controlled by us and are engaged in the same or similar or related trades or businesses, and (iii) one or more qualified publicly-traded partnerships.\n\nOur qualification and taxation as a RIC depends upon our ability to satisfy on a continuing basis, through actual, annual operating results, distribution, income and asset, and other requirements imposed under the Code. However, no assurance can be given that we will be able to meet the complex and varied tests required to qualify as a RIC or to avoid corporate level tax. In addition, because the relevant laws may change, compliance with one or more of the RIC requirements may be impossible or impracticable.\n\nFailure to Qualify as a RIC\n\nIf we were to fail to meet the income, diversification, or distribution tests described above, we could in some cases cure such failure, including by paying a fund-level tax, paying interest, making additional distributions, or disposing of certain assets. If we were ineligible to or otherwise did not cure such failure, or were otherwise unable to qualify for treatment as a RIC, we would be subject to U.S. federal income tax on all of our taxable income at the regular corporate income tax rate and would be subject to any applicable state and local taxes, even if we distributed all of our Investment Company Taxable Income to our stockholders. We would not be able to deduct distributions to our stockholders, nor would we be required to make such distributions. Distributions would be taxable to our stockholders as ordinary dividend income to the extent of our current or accumulated earnings and profits. Subject to certain limitations under the Code, corporate distributees would be eligible for the dividends received deduction, if applicable. Distributions in excess of our current and accumulated earnings and profits would be treated first as a return of capital to the extent of the stockholder’s adjusted tax basis, and then as capital gain. If we fail to meet the RIC requirements for more than two consecutive years and then seek to requalify as a RIC, we generally would be subject to corporate-level U.S. federal income tax on any unrealized appreciation with respect to our assets unless we make a special election to pay corporate-level U.S. federal income tax on any such unrealized appreciation during the succeeding five-year period.\n\nQualification as a RIC\n\nIf we qualify as a RIC and meet the annual distribution requirement, we will not be subject to U.S. federal income tax on the portion of our Investment Company Taxable Income and net capital gain (realized net long-term capital gain in excess of realized net short-term capital loss) that we timely distribute (or are deemed to distribute) to our stockholders. We would, however, be subject to a 4% nondeductible federal excise tax if we do not distribute, actually or on a deemed basis, an amount at least equal to the sum of (i) 98% of our ordinary income for the calendar year, (ii) 98.2% of our net capital gains for the one-year period ending on October 31 of the calendar year (or November 30 or December 31 of that year if we are permitted to elect and so elect) and (iii) any income realized, but not distributed, in the preceding period (to the extent that income tax was not imposed on such amounts), less certain reductions, as applicable. For the calendar years ended December 31, 2025, 2024 and 2023, we incurred $0.3 million, $1.2 million and $1.2 million, respectively, in excise taxes. As of March 31, 2026, there was a capital loss carryforward of $17.3 million.\n\nTaxation of Our U.S. Stockholders\n\nThe following summary generally describes certain U.S. federal income tax consequences of an investment in our shares beneficially owned by U.S. stockholders. If you are not a U.S. stockholder this section does not apply to you. Whether an investment is appropriate for a U.S. stockholder will depend upon that person's particular circumstances. An investment by a U.S. stockholder may have adverse tax consequences. U.S. stockholders are urged to consult their tax advisors about the U.S. tax consequences of investing in the fund.\n\nDistributions\n\nFor any period during which we qualify as a RIC for U.S. federal income tax purposes, distributions to our stockholders attributable to our Investment Company Taxable Income generally will be taxable as ordinary income to our stockholders to the extent of our current or accumulated earnings and profits. Any distributions in excess of our earnings and profits will first be treated as a return of capital to the extent of the stockholder’s adjusted basis in his or her shares of stock and thereafter as capital gain. Distributions of our long-term capital gains, reported by us as such, will be taxable to our stockholders as long-term capital gains regardless of the stockholder’s holding period of the stock and whether the distributions are paid in cash or invested in additional stock. Corporate U.S. stockholders generally are eligible for the 50% dividends received deduction with respect to dividends received from us, but only to the extent such amount is attributable to dividends received by us from taxable domestic corporations.\n\n16\n\n[Table of Contents](#id4d58da65d414707b3cd9972f3050497_7)\n\nAny distribution declared by us in October, November or December of any calendar year, payable to our stockholders of record on a specified date in such a month and actually paid during January of the following year, will be treated as if it were paid by us and received by our stockholders on December 31 of the previous year. In addition, we may elect (in accordance with Section 855(a) of the Code) to relate a distribution back to the prior taxable year if we (1) declare such distribution prior to the later of the extended due date for filing our return for that taxable year or the 15th day of the ninth month following the close of the taxable year, (2) make the election in that return, and (3) distribute the amount in the 12-month period following the close of the taxable year but not later than the first regular distribution payment of the same type following the declaration. Any such election will not alter the general rule that a stockholder will be treated as receiving a distribution in the taxable year in which the distribution is made, subject to the October, November, December rule described above. For the fiscal year ended March 31, 2026, Investment Company Taxable Income exceeded distributions declared and paid, and, in accordance with Section 855(a) of the Code, we elected to treat $21.3 million of the first distributions paid to common stockholders in the fiscal year ending March 31, 2027 as having been paid in the fiscal year ended March 31, 2026. In addition, for the fiscal year ended March 31, 2026, the net capital loss carryforward balance was $17.3 million and no distributions paid in the fiscal year ending March 31, 2027 will be treated as having been paid in the fiscal year ended March 31, 2026.\n\nIf a common stockholder participates in our “opt in” dividend reinvestment plan, then the common stockholder will have their cash dividends and distributions automatically reinvested in additional shares of our common stock, rather than receiving cash dividends and distributions. Any distributions reinvested under the plan will be taxable to the common stockholder to the same extent, and with the same character, as if the common stockholder had received the distribution in cash. The common stockholder will have an adjusted basis in the additional common shares purchased through the plan equal to the dollar amount that would have been received if the U.S. stockholder had received the dividend or distribution in cash. The additional common shares will have a new holding period commencing on the day following the day on which the shares are credited to the common stockholder’s account. The plan agent purchases shares in the open market in connection with the obligations under the plan.\n\nWe may distribute our net long-term capital gains, if any, in cash or elect to retain some or all of such gains, pay taxes at the U.S. federal corporate-level income tax rate on the amount retained, and designate the retained amount as a “deemed distribution.” If we elect to retain net long-term capital gains and deem them distributed, each U.S. common stockholder will be treated as if they received a distribution of their pro-rata share of the retained net long-term capital gain and the U.S. federal income tax paid. As a result, each U.S. common stockholder will (i) be required to report their pro-rata share of the retained gain on their tax return as long-term capital gain, (ii) receive a refundable tax credit for their pro-rata share of federal income tax paid by us on the retained gain, and (iii) increase the tax basis of their shares of common stock by an amount equal to the deemed distribution less the tax credit. To use the deemed distribution approach, we must provide written notice to our common stockholders prior to the expiration of 60 days after the close of the relevant taxable year. For the years ended March 31, 2026, 2025 and 2024, we did not elect to retain long-term capital gains and to treat them as deemed distributions to common stockholders.\n\nSale of Our Shares\n\nA U.S. stockholder generally will recognize taxable gain or loss if the U.S. stockholder sells or otherwise disposes of the shares of our common or preferred stock. Any gain arising from such sale or disposition generally will be treated as long-term capital gain or loss if the U.S. stockholder has held the shares for more than one year. Otherwise, it will be classified as short-term capital gain or loss. However, any capital loss arising from the sale or disposition of shares of our stock held for six months or less will be treated as long-term capital loss to the extent of the amount of capital gain dividends received, or undistributed capital gain deemed received, with respect to such shares. All or a portion of any loss realized upon a taxable disposition of shares will be disallowed under the Code’s “wash sale” rule if other substantially identical shares are purchased within 30 days before or after the disposition. In such a case, the basis of the newly purchased shares will be adjusted to reflect the disallowed loss. Under the tax laws in effect as of the date of this filing, individual U.S. stockholders are subject to a maximum federal income tax rate of 20% on their net capital gain (i.e. the excess of realized net long-term capital gain over realized net short-term capital loss for a taxable year) including any long-term capital gain derived from an investment in our shares. Such rate is lower than the maximum rate on ordinary income currently payable by individuals. Corporate U.S. stockholders currently are subject to federal income tax on net capital gain at the same rates applied to their ordinary income. Capital losses are subject to limitations on use for both corporate and non-corporate stockholders. Certain U.S. stockholders who are individuals, estates or trusts generally are also subject to a 3.8% Medicare tax on, among other things, dividends on and capital gain from the sale or other disposition of shares of our stock.\n\n17\n\n[Table of Contents](#id4d58da65d414707b3cd9972f3050497_7)\n\nBackup Withholding and Other Required Withholding\n\nWe may be required to withhold U.S. federal income tax, or backup withholding, from all taxable distributions to any non-corporate U.S. stockholder (i) who fails to furnish us with a correct taxpayer identification number or a certificate that such stockholder is exempt from backup withholding, or (ii) with respect to whom the Internal Revenue Service (“IRS”) notifies us that such stockholder has failed to properly report certain interest and dividend income to the IRS and to respond to notices to that effect. An individual’s taxpayer identification number is generally his or her social security number. Any amount withheld under backup withholding is allowed as a credit against the U.S. stockholder’s federal income tax liability, provided that proper information is provided to the IRS.\n\nSections 1471-1474 of the Code and the U.S. Treasury and IRS guidance issued thereunder or, collectively, FATCA, generally require that we obtain information sufficient to identify the status of each shareholder under FATCA or under an applicable intergovernmental agreement, or IGA, between the United States and a foreign government. If a shareholder fails to provide the requested information or otherwise fails to comply with FATCA or an IGA, we may be required to withhold under FATCA at a rate of 30% with respect to that shareholder on ordinary dividends it pays. The IRS and the Department of Treasury have issued proposed regulations providing that these withholding rules will not apply to the gross proceeds of share redemptions or capital gain dividends we pay. If a payment is subject to FATCA withholding, we are required to withhold even if such payment would otherwise be exempt from withholding under the rules applicable to foreign shareholders described above (e.g., interest-related dividends). In addition, subject to certain exceptions, this legislation also imposes a 30% withholding on payments to foreign entities that are not financial institutions unless the foreign entity certifies that it does not have a greater than 10% U.S. owner or provides the withholding agent with identifying information on each greater than 10% U.S. owner. Depending on the status of a non-U.S. stockholder and the status of the intermediaries through which they hold their shares, non-U.S. stockholders could be subject to this 30% withholding tax with respect to distributions on their shares and proceeds from the sale of their shares. Under certain circumstances, a non-U.S. stockholder might be eligible for refunds or credits of such taxes.\n\nInformation Reporting\n\nWe will send to each of our U.S. stockholders, after the end of each calendar year, a notice providing the amounts includible in the U.S. stockholder’s taxable income for such year as ordinary income and as long-term capital gain for cash distributions received. In addition, the U.S. federal tax status of each year’s distributions will generally be reported to the IRS (including the amount of dividends, if any, eligible for the preferential rates applicable to long-term capital gains).\n\nRegulation as a BDC\n\nWe are a closed-end, non-diversified management investment company that has elected to be regulated as a BDC under Section 54 of the 1940 Act. As such, we are subject to regulation under the 1940 Act. The 1940 Act contains prohibitions and restrictions relating to transactions between BDCs and their affiliates, principal underwriters and affiliates of those affiliates or underwriters and requires that a majority of the directors be persons other than “interested persons,” as defined in the 1940 Act. In addition, the 1940 Act provides that we may not change the nature of our business so as to cease to be, or to withdraw our election as, a BDC unless approved by a \"vote of a majority of outstanding voting securities,” as defined in the 1940 Act.\n\nIn general, a BDC must have been organized and have its principal place of business in the U.S. and must be operated for the purpose of making investments in qualifying assets, as described in Sections 55(a)(1) through (a)(3) of the 1940 Act.\n\nQualifying Assets\n\nUnder the 1940 Act, a BDC may not acquire any asset other than assets of the type listed in Section 55(a) of the 1940 Act, which are referred to as qualifying assets, unless, at the time the acquisition is made, qualifying assets, other than certain interests in furniture, equipment, real estate, or leasehold improvements (“Operating Assets”), represent at least 70% of\n\n18\n\n[Table of Contents](#id4d58da65d414707b3cd9972f3050497_7)\n\ntotal assets, exclusive of Operating Assets. The types of qualifying assets in which we may invest under the 1940 Act include the following:\n\n(1)Securities purchased in transactions not involving any public offering from the issuer of such securities, which issuer is an eligible portfolio company. An eligible portfolio company is generally defined in the 1940 Act as any issuer which:\n\n(a)is organized under the laws of, and has its principal place of business in, any state or states in the U.S.;\n\n(b)is not an investment company (other than a small business investment company wholly owned by the BDC or otherwise excluded from the definition of investment company); and\n\n(c)satisfies one of the following:\n\n(i)it does not have any class of securities with respect to which a broker or dealer may extend margin credit;\n\n(ii)it is controlled by the BDC and for which an affiliate of the BDC serves as a director;\n\n(iii)it has total assets of not more than $4 million and capital and surplus of not less than $2 million;\n\n(iv)it does not have any class of securities listed on a national securities exchange; or\n\n(v)it has a class of securities listed on a national securities exchange, with an aggregate market value of outstanding voting and non-voting equity of less than $250 million.\n\n(2)Securities received in exchange for or distributed on or with respect to securities described in (1) above, or pursuant to the exercise of options, warrants or rights relating to such securities.\n\n(3)Cash, cash items, government securities or high quality debt securities maturing in one year or less from the time of investment.\n\nAs of March 31, 2026, 97.8% of our assets were qualifying assets.\n\nAsset Coverage\n\nPursuant to Section 61(a)(3) of the 1940 Act, we are permitted, under specified conditions, to issue multiple classes of senior securities representing indebtedness. However, pursuant to Section 18(c) of the 1940 Act, we are permitted to issue only one class of senior securities that is stock. In either case, we may only issue such senior securities if such class of senior securities, after such issuance, has an asset coverage, as defined in Section 18(h) of the 1940 Act, of at least 150%. As of March 31, 2026, our asset coverage on our senior securities representing indebtedness was 213.8%.\n\nIn addition, our ability to pay dividends or distributions (other than dividends payable in our common stock) to holders of any class of our capital stock would be restricted if our \"senior securities representing indebtedness\" fail to have an asset coverage of at least 150% (measured at the time of declaration of such distribution and accounting for such distribution). The 1940 Act does not apply this limitation to privately arranged debt that is not intended to be publicly distributed, unless this limitation is specifically negotiated by the lender. In addition, our ability to pay dividends or distributions (other than dividends payable in our common stock) to our common stockholders would be restricted if our \"senior securities that are stock\" fail to have an asset coverage of at least 150% (measured at the time of declaration of such distribution and accounting for such distribution). When the value of our assets declines, we might be unable to satisfy these asset coverage requirements. To satisfy the 150% asset coverage requirement in the event that we are seeking to pay a distribution, we might either have to (i) liquidate a portion of our portfolio to repay a portion of our indebtedness or (ii) issue common stock. This may occur at a time when a sale of a portfolio asset may be disadvantageous, or when we have limited access to capital markets on agreeable terms. In addition, any amounts that we use to service our indebtedness or for offering costs will not be available for distributions to our stockholders. If we are unable to regain the requisite asset coverage through these methods, we may be forced to suspend the payment of such dividends or distributions.\n\n19\n\n[Table of Contents](#id4d58da65d414707b3cd9972f3050497_7)\n\nSignificant Managerial Assistance\n\nA BDC generally must make available significant managerial assistance to issuers of certain of its portfolio securities that the BDC counts as a qualifying asset for the 70% test described above. Making available significant managerial assistance means, among other things, any arrangement whereby the BDC, through its directors, officers or employees, offers to provide, and, if accepted, does so provide, significant guidance and counsel concerning the management, operations or business objectives and policies of a portfolio company. Significant managerial assistance also includes the exercise of a controlling influence over the management and policies of the portfolio company. However, with respect to certain, but not all such securities, where the BDC purchases such securities in conjunction with one or more other persons acting together, one of the other persons in the group may make available such managerial assistance, or the BDC may exercise such control jointly.\n\nSummary Risk Factors\n\nBelow is a summary of the principal risk factors associated with an investment in our securities.
